Hey guys I have an 88 GXL with a S5 Jspec engine swap. The engine has great compression and 37,000 miles on it. My mods are

Manual Boost Controller (running at 11-13psi)
750cc Secondary Injectors
All Emissions removed and blocked w/ blockoff plates
Wastegate Fully Ported /w new flapper
Full 3 1/8in Turbo Back Exhaust
Tuning with S-AFC

I am ready to get the car back and get it on the dyno but what numbers do u guys with similar setup put down on the dyno and the 1/4 mile. I have been told to expect low to mid 13's in the 1/4 and puttin down 230-245rwhp. Which is about 265hp at the flywheel. Any help would be greatly appreciated. Thanks
Mike

 

BUMP!!!!!!!!!! No one has a similar setup?

 

Im have almost the same setup except that I have a walbro 255 fuel pump stage 3 clutch it will probably run next week let me how you did in the dyno

 

Yeah I have a Cosmo 20B Fuel pump...but yeah I am anxious to see what kind of power I will be making. If you make it to the dyno before me definitely let me know your numbers....and how the car pulls...LOL
Mike

 

i say 230whp and a 13.7 in the 1/4

 

Yeah I could see 230rwhp, but I have seen T2's with less mods run mid 13's with good driving. I think mybe if I kept my 60' time a 2.0 or better then I would be low 13's. Off of this setup right now I would like to be running 13.3-13.5. Anyone got some timeslips of their runs w/ mods similar to mine?

 

i ran a 13.38@ 102.65 mph

mods are in the sig.

that was around noon.....i had ran earlier in the morning and ran 13.4@85mph....(missed 4th)

that was a result of the cooler temp in the morning. as the day went on the temps went up...and i gave up.......sutpid stock intercooler. your set-up will be nice and snappy.....one piece of advice....proper tuning and a fmic will be key power makers and the key to being a reliable powerful car.

 

Thanks alot 86gxlsp I am really looking forward to getting the car back. Your times are great and yeah I know that a FMIC, tuning, and and T-04 Internals can turn my car into a low to mid 12 second monster. But yeah I think with my mods now run low to mid 13's would be fine....I am used to driving a 210hp Streetported Rotary, I cant even imagine what this Jspec Turbo engine will feel like at 12 psi....LOL. Man I have never even rode in a stock T2....LOL.

 

yeah i cant wait to get my first gen S4 on the track and dyno. Im hoping to get in the low 12's. rebuild and streetport, Haltech, act 4 puck clutch, light flywheel and driveshaft, DP and 3 in exhaust, 2 extra 550 injectors, at 12 psi

 

That setup sounds pretty MEAN....LOL. Nah with some good tuning you should make some good power...make sure you let me know how the 12's feel...LOL. I want to get a ride in a Stock T2 before I get my car back so I can just see how fast a stock one is. I hear just bone stock S5 T2's are pretty fast STOCK.

 

so when u goin to the track?

 

First off I gotta get my car bck...should be done the end of this week...and looks like I will have to be using a G-Tech till the warm weather comes bck cuz the track is closed here....Bastards could at least open it up on nice days

 

i'm guessing at the very fastest somewhere between 13.49 and 13.69, thats if your an outstanding driver

 

Yeah those times sound about right....I will do runs with and without drag slicks...to see the difference in times. I cn drive very well and launching wont be a problem...(since thats half the battle anyway....LOL) But yeah with the slicks and a 2.0 60' low 13's is ATTAINABLE. Anybody else think something different.

 

i got 2.0 60 ft on regular street tires with no wieght reduction AT ALL.

with slicks and some weight reduction you should get better then a 2.0 60ft.

its all in the launch.....low are attanible...it may take a few trys

 

I would like to do a little weight reduction but I dont know what to remove from my car. I have nothing at all in the back, the spare tire has been removed, I have 2 lightweight racing seats (stock ones were to heavy), but my full interior is from a S5 Turbo II car. What would low 13's in the 1/4 be in the 1/8 mile....? would it be like low 8's or something?

 

for starters on weight reduction a/c system (the whole damn thing), the factory steel hood, (if you don't have an aftermarket fiberglass or the aluminum turbo hood) lightwieght racing wheels (i recommend OZ racing) upgrade to standard rackand pinion and ditch your p/s pump that otta get ya started.

just a comment, dont take this to heart, why is everyone so concerned with weight issues, i mean as far a power to weight ratio is concerned, you are only going to get the car so light, once you have removed the biggest non essentials you will only be taking off ounces at a time and unless you a strictly drag racing the is essentially less benefit in removing **** than there is in simply increasing horespower

 

Yeah I have a an Aluminun Turbo II Hood...I have 14lb Lighweight 17in racing wheels...made by Enkei. Yeah ur right there is only so much to do. I will definitely see my low 13's though...the I will have to post some pics of the car and the times....I doubt anyone "understands" how hot my car is....LOL.

 

My friends used to have a stock one that i used to ride in all the time. It felt fast asa hell to me but that might be because I was comparing it to my 12a. Now Hes got a ported 3rd gen with all kinds of **** on it. That thing is scary fast

 

Yeah a T2 compared to a 12A is a big difference...lOL I just wanted to get a ride in a stock one somehow before i rode in my modded one.

 

I have a jdm s4 engine with, 3" straight pipe, 720 secondairies, FCD, emissions removed, dual stage coolingmist waterinjection, stock TMIC,manual boost controller (10-11psi) soon to be ported wastegate. Tranny came with a short shifter and I have a set of 295 off-set rims on the back for the track. 1 more week till engine is in the vert, what do you guys think I'll run and hp estimates, this is my first 13bt so the hp numbers I"m not familar with yet.

Thanks, Tony

EDIT: I have the stock TII fuel pump, I should upgrade?

 

I say w/ good driving low to mid 13's. Those are the numbers I am shooting for as well. But I definitely know for a fact you should be in the 13's. If you are horrible you may get a low 14 but u shouldnt.
